SUPPORTING MEANS FOR LAMB SHADES AND CHIMNEYS.

Specification of Letters Patent.

Patented Nov. 8, 1910.

Application filed July 27, 1910. Serial No. 574,144.

T 0 all whom it may concern:

Be it known that I, Miorranr. Doxorron, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Supporting Means for Lamp Shades and Chimneys, of which the following is a specification.

The object of my invention is the provision of a support or holder for shades and chimneys, which especially shall be adapted for use in connection with inverted gas or other burners, said support to be so constructed that the parts comprising the same may be separated when necessary to allow the substitution of another shade.

My invention consists in certain novelties of construction and combinations of parts as hereinafter set forth and claimed.

The accompanying drawing illustrates two examples of the physical embodiment of the invention constructed and arranged according to the best modes of procedure I have so far devised for the purpose.

Figure 1 is a vertical section of a shade, chimney, burner frame and the first example of the supporting means. Fig. 2 is a view in perspective of the clamping ring shown in Fig. 1. Fig. 3 is a view in perspective of the shade and chimney supporting ring. Figs. 1, 5 and 6 illustrate the second example of the supporting means by views similar to those showing the first example.

Referring to both examples, the numeral 1 designates a burner as a whole of a well known type having a concavo-convex frame 2 with a flange 3 having holes therethrough to receive threaded set-screws 4t, the gas delivery pipe 5 and the burner proper 6 being rigidly secured to the frame. The shade 7 is without a collar and has a relatively large circular opening, and the chimney 8 has a circular exteriorly projecting flange 9 and is located mainly within and concentric with the shade.

The number 10 designates the circular supporting ring; 11, an outwardly extending flange of larger diameter than the circular opening of the shade, and its external surface matches the interior surface of the shade adjacent to the opening; 12, the neck of the ring of smaller diameter than the opening of the shade so it can pass through and extend above the edge of the shade bounding the opening; 13, external threads upon the neck formed in any suitable way; 1 1, an inwardly projecting circular flange at the top edge of the neck adapted to receive and support the chimney through the me dium of the flange 9 at one end thereof; and 1.5 is a circular clamping ring having an exteriorly projecting flange l6 and a neck 17 provided with threads 18 upon its inner surface. In the first example (Figs. 1, 2 and 3) the neck adjacent to its edge has a plurality of slots 19 each in communication at one end with an opening 20 in the edge of the neck, the function of said openings being to permit the passage of the screws 4 of the burner so they may enter the slots and support the shade and chimney. In the second example (Figs. 4, 5 and 6) the neck is fashioned to form an external circular recess or groove for the reception of the ends of the set-screws 4: of the frame, which screws support the shade and chimney.

To assemble the parts the neck of the supporting ring is passed upwardly through the opening in the shade until the flange 11 frictionally engages the interior surface of the shade adjacent the opening; the clamping ring is then screwed upon the neck of the supporting ring until its flange 16 engages the exterior surface of the shade adjacent to the opening. The chimney is adjusted to position through the opening of the shade at the top and its flange 9 engages the inwardly projecting flange 14 of the supporting ring. In the first example the shade is detachably secured to the frame of the burner by the set-screws in the slots, with which they constitute a bayonet joint of a well known form and operation. In the second example the shade is adjusted and supported by the set-screws engaging the surface of the metal in the circular recess of the neck in a well known way.

The preferred type of construction is shown by the first example, inasmuch as when the screws engage the slots the shade is concentric with the burner, whereas in the second example the unequal adjustment, of the screws will displace the shade out of center with the burner or cause one edge to lie in a horizontal plane above the plane of the opposite edge. Moreover, in the first example no manipulation of the screws is necessary and the shade can easily and quickly be detached from and adjusted to the burner frame.

From the foregoing description taken in connection with the drawing it becomes clear that I have provided an improved supporting means for shades and chimneys which will permit the easy substitution of a shade and will maintain the shade and chimney in position concentric with the burner. The supporting means, including the two rings, may be secured to the shade and constitute with it a complete article of manufacture.

What I claim is:

1. Supporting means for a lamp shade and chimney comprising a supporting ring having an exteriorly projecting flange, a neck exteriorly threaded, and an inwardly projecting portion at the top edge of the neck to receive the chimney; and a clamping ring having an eXteriorly projecting flange, a neck interiorly threaded, and means adjacent the top edge of the neck adapted to be engaged by the attaching means of a burner frame.

2. Supporting means for a lamp shade and chimney comprising a supporting ring having an exteriorly projecting flange, a neck exteriorly threaded, and an inwardly projecting portion at the edge of the neck to receive the chimney; and a clamping ring having an exteriorly projecting flange, and a neck interiorly threaded and provided adjacent its top edge with open slots to receive projecting means in connection with a burner frame.

3. Supporting means for a lam shade and chimney comprising a supportlng ring having an exteriorly projecting flange, a

neck exteriorly threaded, and an inwardly projecting portion at the edge of the neck to receive the chimney; and a clamping ring having a neck interiorly threaded and means adjacent the top edge of the neck adapted to be engaged by the attaching means of a burner frame.

4. Supporting means for a lamp shade and chimney comprising a supporting ring having an exteriorly projecting flange, a neck exteriorly threaded, and an inwardly projecting flange at the edge of the neck to receive the chimney; and a clamping ring having a neck interiorly threaded and provided adjacent its top edge with open slots to receive projecting means in connection with a burner frame.

5. The combination with a lamp shade having an opening, of a supporting ring with a flange 11, a neck exteriorly threaded, and an inwardly projecting flange to support a chimney; and a clamping ring having a neck interiorly threaded, and means adjacent the top edge of the neck adapted to be engaged by the attaching means of a burner frame.

6. The combination with a lamp shade having an opening, of a supporting ring with a flange 11, a neck exteriorly threaded, and an inwardly projecting flange to support a chimney; and a clamping ring having a neck interiorly threaded and provided with open slots to receive projecting means upon a burner frame.

In testimony whereof I affix my signature in presence of two witnesses.

MICHAEL DONOHOE.
